2003 EX - Running Too Rich

Recommended Posts

[if this should go in the Accord forum, feel free to move it]


2003 EX V6


I've got an MIL and codes P0172 & P0175 (system too rich, banks 1 & 2, respectively). About a year ago, I had the same codes pop up. My mechanic tested the EGR system, fuel pressure, MAP, etc., and ultimately replaced the EGR valve. Everything was fine and I had no problems until recently. Any thoughts? I'm hoping that there's a repair I can do myself this time around.
